Democrats say three provisions in the Republican $1.5 trillion tax bill violate Senate rules and will likely be removed before that chamber votes on the measure.

The House approved the legislation Tuesday. But this means the House will have to vote again on the legislation once it's been amended and approved by the Senate.

Senate passage was expected Tuesday night or early Wednesday. GOP House Majority Leader Kevin McCarthy's office says the House would reconsider the bill Wednesday morning and send it to President Donald Trump for his signature.

Democrats said the Senate parliamentarian had found three items that violated Senate rules.

These included one provision that would let families use tax-advantaged 529 accounts for home-schooling expenses.
